Abstract

The observation of the surface structure on single crystalline CeO_1-xF_xBiS₂ (x = 0.5, and 0.7) was performed successfully using a scanning tunneling microscopy. In the sample with x = 0.5, the square lattice composed of Bi atoms was observed. In addition, defects of the surface atoms and streaks were detected on the surface as in the case of NdO_0.7F_0.3BiS₂ single crystal. With further F doping, the surface structure of sample with x = 0.7 showed a novel structure, termed by the "bone" structure. This result suggests that the F concentration affects the surface structure.
